To all whom 'it may concefm v Be it known that I, Jmms Warmes, of the city of Minneapolis, county of Hennepin, and State of Min-l nesota, have invented a new and useful Improvement in Gange-Cocks for- Steam-Boilers; and .I do hereby declarethat the following is a full, clear, and exact description thereof, which will enable those skilled in the' art to make and use the same,reference being had to the accompanying drawing, forming part of this specifcation, in which-.

Figure 1 is a longitudinal sectional few of my invention.

The object of my invention is to produce a gangecock that shall, with certainty, tell the exact height of the water in the boiler, from the top of the ues to the top ofthe boiler. l A- is the main. stock, which screws into the boiler. B, the-pipewhich dischargeswater or steam from the boiler.

C, the pipe which receives the water or steam from theinside of the boiler.

D, the handle, with which the cock is operated.

E, valve.

F, the pin, to stop up the end of the valve-case.

G, a guard packing-ring, between the valve-case and the stationary stock A.

H, holes through the valve-case, to let wateror steam out iio--thed'ischarge-pipe B'. I, stulllng-box. K, valve-case.

L, valve-seat.

Operation. The pressure 'in the boiler will press the;valvec ase K against theguard-ring G, making a tight joint, and

will also press the valve on to the valve-seat L. This makes all tight. Take hold of handle D,'pull out on its outer end, which will throw the valve off its seat,

and the steam or water will pass out through the out- 1er B. Then tum the handle D nu the ena ofinlet C shall strike the surface of the watergand you will know when the water is in the boiler. The handle D being just as long as the inlet-pipe C, and standing in the same direction, of course the outer end of the handle D will show exactly when the water is in the boiler.

What I claim as my invention, and desire to secure by Letters Patent, is-

A gauge-cock, consisting of stock A, valvecas'e K valve E, valve-scat L, inlet O, and lever D, arranged substantially asdescribed.
